Abstract

The electric circuit board (1) has at least one plug contact element (3,4) oriented with its longitudinal axis parallel to the surface of the circuit board. The plug contact is connected to a metallic connector region (5,6) on the circuit board surface by a reflow solder process. A recess (7,8) on the circuit board is provided for the contact element. For correct positioning and fixing, at least part of the plug contact is located in the recess from the time it is mounted on the circuit board until the solder point hardens or sets. Independent claims also cover a method of manufacturing the circuit board.

Description

Die Erfindung betrifft eine elektrische Leiterplatte mit mindestens einem mit seiner Längsachse parallel zur Leiterplattenoberfläche orientierten und mit dieser durch einen Reflow-Lötprozeß verbundenen, vorzugsweise rund ausgeführten Steckkontaktelement.The invention relates to an electrical circuit board with at least one oriented along its longitudinal axis parallel to the PCB surface and with this is connected by a reflow soldering process, preferably round executed plug contact element.

Der Reflow-Lötprozeß dient zur Herstellung einer Lötverbindung oberflächenmontierbarer, sog. SMD-Bauteile mit Anschlußbereichen einer Leiterplatte. Dazu wird die Leiterplatte an den später die Anschlußbereiche bildenden Lötflächen zunächst mit einer Lötpaste versehen, was z.B. in einem Siebdruckverfahren erfolgen kann. Danach werden die Schaltungskomponenten - in der Regel durch eine automatische Bestückungsmaschine - mit ihren Anschlüssen in die Paste der entsprechenden Lötfläche gedrückt.
Die so bestückte Leiterplatte durchläuft danach in einer Reflow-Lötanlage ein Temperaturprofil, in dem zunächst bestimmte Bestandteile der Lötpaste ausgasen, bevor das enthaltene Flußmittel aktiviert wird, und schließlich in der Aufschmelzzone das in der Lötpaste enthaltene Lotmetall aufgeschmolzen und so die Lötverbindung hergestellt wird.
In dem gesamten Prozeß vom Bestücken der Leiterplatte bis zum Erstarren der Lötverbindung werden die Bauteile allein durch die Adhäsionskraft der Lötpaste in ihrer Position gehalten. Dies ist möglich, da die Bauteile in der Regel relativ klein und leicht sind und jeweils mit mindestens zwei Anschlußkontakten versehen sind.
Oft ist es aber erforderlich, zur späteren Verbindung der so hergestellten elektronischen Schaltung mit anderen Geräten Schnittstellen in Form von Steckverbindern vorzusehen. Kommen bei diesen Steckverbindern insbesondere Steckkontaktelemente zum Einsatz, die mit ihrer Längsachse parallel zur Leiterplattenoberfläche montiert werden müssen, so bietet die eine Kontaktstelle auf der Leiterplatte, die für diese jeweils vorhanden ist, keine Möglichkeit zur ausreichenden Fixierung derselben in der gewünschten Lage. Insbesondere rund ausgeführte Steckkontaktelemente, die zumeist in Gestalt massiver Drehteile vorliegen, sind durch ihre langgestreckte, zylindrische Form sowie eine relativ große Masse gekennzeichnet. Dies bewirkt aber bei den unvermeidlichen Erschütterungen, denen die Leiterplatte im Prozeßverlauf ausgesetzt ist, das Auftreten von Kräften und Drehmomenten, die die von der einen Lötpastenfixierung aufzubringende Haltekraft bei weitem übersteigen.The reflow soldering process serves to produce a soldered connection of surface-mountable, so-called SMD components with connection areas of a printed circuit board. For this purpose, the printed circuit board is first provided with a solder paste on the soldering areas later forming the connection areas, which can be done, for example, in a screen printing process. Then the circuit components - usually by an automatic assembly machine - are pressed with their connections into the paste of the corresponding soldering surface.
The printed circuit board assembled in this way then runs through a temperature profile in a reflow soldering system, in which certain components of the soldering paste first outgas before the flux contained in it is activated, and finally the soldering metal contained in the soldering paste is melted in the melting zone, thus establishing the soldered connection.
In the entire process, from assembling the circuit board to solidifying the solder joint, the components are held in their position solely by the adhesive force of the solder paste. This is possible because the components are generally relatively small and light and are each provided with at least two connection contacts.
However, it is often necessary to provide interfaces in the form of plug connectors for later connection of the electronic circuit thus produced to other devices. If in particular plug contact elements are used with these connectors, which have to be mounted with their longitudinal axis parallel to the surface of the circuit board, the one contact point on the circuit board, which is available for each of these, does not offer the possibility of adequately fixing the same in the desired position. In particular, round plug-in contact elements, which are mostly in the form of solid turned parts, are characterized by their elongated, cylindrical shape and a relatively large mass. However, with the inevitable shocks to which the printed circuit board is exposed in the course of the process, this causes the occurrence of forces and torques which far exceed the holding force to be applied by the solder paste fixation.

Aufgabe der vorliegenden Erfindung ist es daher, eine für einen Reflow-Lötprozeß vorgesehene Leiterplatte bereitzustellen, bei der auf der Leiterplatte liegend zu montierende Steckkontaktelemente in einem Arbeitsgang und von den gleichen Vorrichtungen bestückt werden, wie die übrigen Schaltungskomponenten, bei denen es sich insbesondere um SMD-Bauteile handelt, und die Mittel aufweist, um diese Steckkontaktelemente in der vorgesehenen Position bis zur Erstarrung der Lötverbindung zu fixieren. The object of the present invention is therefore one for a reflow soldering process to provide the intended circuit board, on the circuit board plug-in contact elements to be assembled in one operation and from the same devices as the rest Circuit components, which are in particular SMD components acts, and has the means to these plug contact elements in the fix the intended position until the solder joint solidifies.

Die Erfindung löst diese Aufgabe ohne Zuhilfenahme zusätzlicher mechanischer Bauteile, Klebemedien oder ähnlichem, indem sie in der Leiterplatte Ausnehmungen vorsieht, deren Längen und Breiten so bemessen sind, daß sich im Zusammenwirken mit den Längen und Querschnitten der Steckkontaktelemente eine für die Lötung optimale Auflage derselben auf der Leiterplatte ergibt. In einer besonders vorteilhaften Ausführungsform sind die Steckkontaktelemente dabei rund ausgeführt und mit abschnittsweise unterschiedlichen Durchmessern versehen.The invention solves this problem without additional help mechanical components, adhesive media or the like by being in the Printed circuit board provides recesses, their lengths and widths so dimensioned are that in cooperation with the lengths and cross sections of the Plug contact elements an optimal support of the same on the soldering PCB results. In a particularly advantageous embodiment, the Plug contact elements are round and with sections different diameters.

Weitere Ausgestaltungen und zweckmäßige Weiterbildungen des erfindungsgemäßen Gegenstandes sind in den zusätzlichen Unteransprüchen angegeben und gehen auch aus der nachfolgenden Beschreibung des in der Zeichnung dargestellten Ausführungsbeispiels hervor. Dabei zeigen:

Further refinements and expedient developments of the subject matter according to the invention are specified in the additional subclaims and are also apparent from the following description of the exemplary embodiment shown in the drawing. Show:
Fig. 1:
a section of an electrical circuit board according to the invention in the top view of its top
Fig 2:
a round, pin-shaped plug contact element on an electrical circuit board according to the invention in longitudinal and cross section

Wie in Fig. 1 zu sehen sind auf der Oberseite einer erfindungsgemäßen, elektrischen Leiterplatte 1 SMD-Komponenten 2a, 2b, 2c, ... montiert, die auf Lötflächen repräsentierenden Anschlußbereichen 2a', 2a'', ... positioniert sind. Außerdem sind in dem dargestellten Ausschnitt zwei rund ausgeführte, stiftförmige Steckkontaktelemente 3 und 4 zu sehen, die auf der Leiterplatte 1 so positioniert sind, daß ihre mit der Leiterplatte zu kontaktierenden Endabschnitte 3'und 4' auf Lötflächen 5 und 6 aufliegen. Die freien Abschnitte dieser rundstiftförmigen Steckkontaktelemente, die zur späteren Kontaktierung mit den entsprechenden buchsenförmigen Steckkontaktelementen vorgesehen sind, liegen dabei in Schlitzen 7 und 8, die sich parallel zu ihrer Längsachse in der Leiterplatte 1 erstrecken. In dieser gegenüber der Leiterplattenoberfläche vertieften Lage sind die rundstiftförmigem Steckkontaktelemente bei weitgehend waagerechter Haltung der Leiterplatte während des nachfolgenden Handlings durch die Schwerkraft in ihrer Lage fixiert.
Die Länge und Breite der Schlitze in der Leiterplatte sowie die abschnittsweise unterschiedlichen Durchmesser der rundstiftförmigen Steckkontaktelemente sind aufeinander so abgestimmt, daß nicht nur eine ausreichende Fixierung der rundstiftförmigen Steckkontaktelemente bis zum Erstarren der Lötverbindung sowie eine korrekte Position derselben im fertigen Produkt gewährleistet ist, sondern auch eine Auflage der zu kontaktierenden Endabschnitte 3' und 4' auf den Lötflächen 5 und 6, die ein optimales Lötergebnis erwarten läßt.
Nach Fertigstellung der Lötung wird der Abschnitt 1'' der Leiterplatte 1 entlang einer Linie 10 von dem Abschnitt 1' abgetrennt, auf dem die elektronischen Bauelemente und Steckkontaktelemente angelötet sind. Die rundstiftförmigen Steckkontaktelemente 3 und 4 werden durch diese Maßnahme freigestellt. Entlang der Linie 10 der vorgesehenen Trennung kann schon bei der Herstellung der unbestückten Leiterplatte eine Schwächung z.B. in Form einer Kerbfräsung eingebracht werden.As can be seen in FIG. 1, SMD components 2a, 2b, 2c, ... are mounted on the top of an electrical printed circuit board 1 according to the invention, which are positioned on connection areas 2a ', 2a'', ... representing soldering areas. In addition, two round pin-shaped plug contact elements 3 and 4 can be seen in the section shown, which are positioned on the circuit board 1 so that their end sections 3 'and 4' to be contacted with the circuit board rest on soldering surfaces 5 and 6. The free sections of these round pin-shaped plug contact elements, which are provided for later contacting with the corresponding socket-shaped plug contact elements, lie in slots 7 and 8, which extend parallel to their longitudinal axis in the printed circuit board 1. In this position, which is recessed in relation to the surface of the printed circuit board, the round pin-shaped plug contact elements are fixed in their position by gravity when the printed circuit board is kept largely horizontal during subsequent handling.
The length and width of the slots in the printed circuit board as well as the different diameters of the round pin-shaped plug contact elements are matched to one another so that not only is sufficient fixation of the round pin shaped plug contact elements until the solder connection solidifies and a correct position thereof in the finished product is ensured, but also one Support of the end sections 3 'and 4' to be contacted on the soldering surfaces 5 and 6, which allows an optimal soldering result to be expected.
After completion of the soldering, the section 1 ″ of the printed circuit board 1 is separated along a line 10 from the section 1 ′ on which the electronic components and plug contact elements are soldered. The round pin-shaped plug contact elements 3 and 4 are exempted by this measure. A weakening, for example in the form of a notch cut, can already be introduced along the line 10 of the proposed separation during the manufacture of the bare printed circuit board.

Die erfindungsgemäße Leiterplatte eignet sich insbesondere auch zur Realisierung mehrerer, voneinander unabhängiger, gleicher oder unterschiedlicher Schaltkreise, die nach Fertigstellung der Lötung voneinander mechanisch getrennt werden.
Als Steckkontaktelemente können dabei selbstverständlich neben den im dargestellten Ausführungsbeispiel gezeigten stiftförmig und rund ausgeführten ebenso auch buchsenförmige und/oder solche mit anderen als runden Querschnittsformen zum Einsatz kommen.The printed circuit board according to the invention is also particularly suitable for implementing a plurality of independent, identical or different circuits which are mechanically separated from one another after completion of the soldering.
In addition to the pin-shaped and round designs shown in the exemplary embodiment shown, socket-shaped and / or those with cross-sectional shapes other than round can also be used as plug-in contact elements.

Mit besonderem Vorteil kann die erfindungsgemäße Leiterplatte bei einem Herstellungsverfahren eingesetzt werden, bei dem die Bestückung der Leiterplatte ausschließlich aus SMD-Komponenten und den Steckkontaktelementen besteht. Bei einem solchen Herstellungsverfahren werden die Steckkontaktelemente dann von den gleichen automatischen Bestückungsmaschinen wie die SMD-Komponenten und in einem Arbeitsgang mit diesen bestückt.The circuit board according to the invention can be particularly advantageous for one Manufacturing process are used in which the assembly of the PCB made exclusively from SMD components and Plug contact elements exist. In such a manufacturing process then the plug contact elements of the same automatic Pick and place machines like the SMD components and in one operation equipped with these.
